Berry Botanic Garden was a botanical garden in southwest Portland, Oregon, in the United States. In addition to large collections of alpine plants, rhododendrons, primulas, lilies, it was known for its plant-conservation program and its large seed bank that protects rare or endangered plants of the Pacific Northwest. The seed bank, formally established in 1983, was thought to be the first in the U.S. that was devoted entirely to preserving rare native plants.
